This is a retrospective chart review examining patients over the age of 18 years who have undergone operations for congenital heart disease. The primary interest of the study is to look at the breakdown of our adult congenital program in regards to location, personnel, and case type. All charts reviewed will be of patients who had their surgery at Children's Healthcare of Atlanta or Emory University between January 1, 2000 and December 31, 2007. We will review approximately 350 charts for this study.
